How this service works
Website hosted for free through pinggy.io> <meta name=
Output
Returns the original URL, a receipt object confirming the verification transaction, a 'supported' string indicating whether the claim is backed by the page content, and an array of cross-reference objects with supporting evidence or related links.
Example use cases
Fact-checking a news article claim
“Check if the article at https://bbc.com/news/article-12345 actually supports the claim that 'global temperatures rose by 1.5 degrees last year' — I want to know if the page backs that up.”
Validating a product page promise
“Verify whether the product page at https://store.example.com/product/x really claims that the battery lasts 48 hours — I need confirmation before I cite it in my report.”
Cross-referencing a citation source
“Can you check if https://research.org/study-2024 supports the statement 'moderate exercise reduces heart disease risk by 30%'? I need to know if it's a valid reference.”

Endpoint
POSThttps://idask-37-255-229-96.run.pinggy-free.link/verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify whether a specific web page actually supports a given claim or statement, especially for fact-checking, citation validation, or content auditing workflows. Prefer this over general web scraping when the goal is binary claim validation with a structured receipt and cross-reference output rather than raw content extraction.
Side effects
- URL is unreachable or returns an error (404, 500) — verification cannot proceed
- Claim provided does not match any content on the page — 'supported' returns negative or unsupported
- URL points to non-textual content (PDF, image, video) that cannot be parsed for claim verification
- Network timeout when fetching the target URL
- Malformed URL input causes validation error before request is made
